The BC-348 works as you described: The LO is on the high side for the
three lowest bands, and on the low side for the top three bands. The
BC-312 is a different animal. The LO is on the high side on all six
bands. --Ed

Ed,

I re-read the book carefully, and I found the explanation in the adjustment
section, not in the theory of operation section as I was expecting.

At page 126 it clearly states that the oscillator is on the low side for the
three higher frequency bands and on the high side for the three lower frequency
bands.

Sorry for the useless noise, I should have read the book more carefully.

Thank you for your availability anyway.
